AWS JAVA dynamoDB enhanced client putItem class cast exception

Question

When I used enhanced client to put but it throws class cast exception.

DynamoDbTable<Tableclass> recordTable = enhanceClient.table(tableName, Tableclass.class);

Tableclass tableclass = new Tableclass();
tableclass.setid(1);
tableclass.setname("myname");
recordTable.putItem(tableclass);

It gives me error java.lang.ClassCastException: com.db.dynamo.Tableclass cannot be cast to com.db.dynamo.Tableclass

I'm getting the same issue with aws sdk version 2.16.45. Did you ever figure this out? — Wan Li

In my case, this post regarding spring devtools solved my problem: stackoverflow.com/a/64350067/1612280 — Wan Li

This worked for me SpringBoot - Java AWS SDK 2 DynamoDB Enhanced Client and devtools problem

So basically the issue was with spring dev tools and its class loader(2 in number), so you can either remove it or move dynamo to the same class loader.
